People look at these giant facilities and think they will never shut down. That is 100% untrue. Its a spreadsheet decision - does it make money or not. Its also about liability and risk, and there is much more of that in California for an oil company than in friendlier places.
Marathon shut there refinery down in California. It was not quite as big but close - 150K BPD vs 250K BPD for the Chevron facilities. Its not just California - several refineries have been shuttered. There old, and expensive to maintain. No one is building new ones for regulatory reasons. Might be cheaper to build a new one in Columbia or Guyana or Mexico and ship refined product instead.
2020-- "Elected officials, union leaders, industry representatives and environmentalists are expressing concern about the hundreds of workersset to lose their jobs at California's fourth-largest refinery in the coming months. That's after Marathon Petroleum announced over the weekend that it plans a permanent halt to processing crude oil at its Martinez plant."

I live in Contra Costa County and have driven near that refinery, which is still there and has been converted into a renewables processing facility. Granted this press release uses “closing” in a confusing way, but they mean the deal was completed.

Chevron is still in Richmond. Phillips 66 is still in Rodeo. PBF is still in Martinez. Chevron is still in San Ramon for that matter. They already moved about 2000 jobs to Houston at a time when they hadn’t decided to move HQ, and right now there don’t seem to be any plans to move any more jobs other than C-suite.
